The incidence of mechanical complications of acute coronary syndromes (ACS) needing cardiac surgery has reduced significantly in the last years due to early diagnosis and treatments. Covid-19 pandemic, however, would generate in the patients a sense of fear regarding access to the ERs so they probably underestimate symptoms such as chest pain or angina equivalents until situation does not became critical. In this way, this behaviour could create a vast pool of patients who will enter the hospital in much more critical situations and with mechanical complications of an evolving ACS needing cardiac surgery treatment.
Scimitar syndrome is rare malformation defined as partial or total anomalous pulmonary venous return of the right lung veins to the inferior vena cava just above or below the diaphragm. Severe forms of the disease are diagnosed in infancy and childhood . However, because of the mild form of the syndrome in adult patients, they remain asymptomatic and few cases are reported in the literature. We report an unusual presentation of this syndrome mimicking unstable angina in one of the two described cases.
